The family is considering three regime structures: remaining tax-resident in California; relocating to Singapore; or a split where Singapore serves as primary residence and Taipei as a secondary (sub-183-day) base. We model all three against a single affluent-tier lifestyle.

Note
Worldwide regime with CA's 13.3% top-bracket surcharge compresses returns on the highest tier.
Territorial regime excludes foreign-sourced portfolio returns; headline rate ~22%, effective lower after deductions.
Combines SG territorial base with Taiwan non-resident status. Requires careful day-count and banking custody planning.
Illustrative projection · Production deployment runs the Monte Carlo against the client's actual portfolio mix, realised/unrealised gains, state-residency day counts, and bespoke expense curve. Assumptions printed on page two of the client deliverable.

Executive summary

Based on the family's $8.2M liquid position and target affluent-tier lifestyle, a Singapore-primary split-residency structure with Taipei as secondary base produces the strongest thirty-year wealth preservation outcome — a projected +$5.9M versus status quo California residence after conservative tax and investment-return assumptions.
